The disposal price has been reduced. Member discounts are not applicable. 2023/12/13 Sales price 138,000 yen Maintenance completed! Newcomb tube mono prime. An output of about 12W is output using a 6V6 output tube. It has an adjustment function for a total of 36 fine phono curves, 6 low frequencies and 6 high frequencies. The stylish look reminiscent of Old Marantz, such as the hood on the back, is irresistible. Since the input terminals are on the bottom, it is necessary to devise how to insert the RCA cable. The standard LEVEL position is M. Adjust the volume with LOUDNESS. SELECTOR's RUMBLE FILTER is valid only for PHONO. ※The hood is fitted very tightly, so it cannot be removed normally. There is a feeling of use due to appearance, dullness, small scratches, abrasions, etc. (Murakoshi Yoichi)
